makefile patch

Thanos in at least build version 0.41.0-1 causes panics once grpc calls to the sidecar or store component are made. This appears to be an issue known in upstream (https://github.com/thanos-io/thanos/issues/8543) but the fix requires the use of the `-tags slicelabels` go build flags. I've used the attached patch to build the port and now thanos appears stable.
